I understand what you're saying. Basically I would be upgrading to essentially a diamond saber to do what I want to do with it.
No no no. You can get a MLS in forum colors, I have several in my collection. All the Emerald board does is allow for variable resistance to be applied in order to change the emitted color. If you know that you only want the one color, you can add a fixed resistance to the (+) of the individual LED in order to limit its output. If I remember, I'll try to get you a pic of what I'm talking about.
Also, if you went to Diamond or Emerald, you would have a cluster LED consisting of Red, Green, Blue, and White/Amber. Hence RGBW/RGBA. IMO, the single LEDs are plenty bright, but to each their own.
I'm not sure if they offer such a setup, but if I'm understanding what you want (Tri-Cree PO with red/silver FoC?) then I think they can do a cluster of 2Red and 2Amber LEDs. If they can, then it is just a matter of wiring the board for FoC to turn off one color during the Flash. I think PO is R+A. I also think that PO flash to FO would look best.
But again, I have limited knowledge of electronics, so you might try emailing US to see (a) if it's doable and (b) how much.
